Will the data plate show exactly which transmission it is, or must the case be measured for that?
I have a paper showing three types, FX, MX and HX.
I´m almost sure that the data tag on my transmission starts with PBB-
Looking at the drawing, are there two loose tubes to the oil pumps? On my transmission there is only one loose tube, on the aft side. The front side is just a fixed tube connected to a larger module.

The data plate will only show what it came from the factory with. There was one automatic option in '58, an MX unless it was an export. It would then have a two speed Fordomatic. The code should be a PBL-* for the 352 engine. If it's a PBB-* it's a 430 transmission.

It appears to be the correct transmission. Why the filter doesn't fit is still a mystery. Even if you are going to reuse the original filter I would still contact Rockauto and see about exchanging the Pioneer filter for an ATP B-41 filter and see if there's a difference.

So in the near future i will have to buy fresh fluid for the rebuild transmission. Now that it will have modern friction materials, there should be no reason to go with type F (which we don't have over here) or type A fluid anymore i think. Would a modern mineral fluid not be a better option?

I had my transmission rebuilt, last year, by a shop that specializes in a lot of the older Ford transmissions. When I picked up the car, I asked them what fluid I should use in the transmission. They told me they filled it with DEX/MERC and that is what I should use.
We'll see what others on the site have to say.

Would not put Dexron / Mercon in my transmission, thank you . Will stick with Ford Type F . ( Type F replaced type A many many years ago ) .

" Type F should be used in transmissions , Ford 1979 and earlier models where type F is specified in the owners manual . Type F fluid differs in its frictional properties as they relate to the design of certain Ford automatic transmissions . The number of, composition of , and pressure on the clutch plates requires a fluid with different frictional properties to a Dexron 11 fluid, to ensure accurate trouble free transmission operation.

This according to the lubricants handbook.

But the handbook is considering the original transmission with its original clutch material. On a rebuild transmission, the clutches use modern friction material,
which doesn't require the type F.
